Alessandro, a few additional questions came up ;):
I got:
class LessonsCrudController(FilteredCrudRestController):
model = Lesson
__table_options__ = {...}
__form_options__ = {...}
def inject_event(self, *args, **kw):
log.debug('inject_event')
for a in args:
log.debug(a)
for k in kw:
log.debug('%s: %s' % (k,kw[k]))
def __init__(self, *args, **kw):
super(LessonsCrudController, self).__init__(*args, **kw)
before_validate(self.inject_event)(self.post)
And that is what I got on the logs:

So you see, the hook gets called very often! It's not event a constant
number, at first I counted 6 calls, now its more than 10.
And the arguments are (not merely wrong but) unexected both packed in args
like args = [[], {}].
What am I doing wrong NOW? :D
Thanks a lot,
best wishes,
Moritz
